A Comprehensive Guide To Plan, Manage, and Execute a Successful SAP BW Implementation Project – Part 1

Bjarne BergLenoir-Rhyne College

2

In Part 1…

• Writing your SAP BW business case • Defining the scope of your implementation• Writing a milestone plan• Developing your staffing plan• Budgeting• On-boarding and training• Writing your workplan• Monitoring the progress of your project• Monitoring quality / instituting a formal approval process• Why you need an SAP BW “user acceptance group”

3

In Part 2…

• The blueprinting phase Leveraging the standard content Modeling for your solution Deliverables

• The realization phase Best practices for managing the implementation of ODS and InfoCubes Managing the environments and transports Managing unit, system, integration & stress testing of SAP BW

• The implementation phase Executing the cut-over to production Conducting end-user and power user training Establishing the end-user support organization Post-implementation review and next steps

4

What We’ll Cover…

• Writing your SAP BW business case • Identifying your requirements, scope, and plan-of-attack • Staffing your project: lessons and examples• Budgeting: how much? and for how long?• Final preparations: on-boarding, writing the workplan, etc. • Wrap-up

5

Writing the Business Case

• The business case must be aligned with some concrete business benefits

• The best way to write a business case is to align it with one of these areas:

Money

Strategy

Reducing time and effort of delivery

Improved information quality and access for end users

6

Example Business Benefits of SAP BW

Users get earlier access to information

Load times in BW are less than traditional,custom- developeddata warehouses

Business users need a high Availability solution

Information Access

Users spend less time on reconciling data, and moretime analyzing it.

BW is “closer” to the source system, and more accurately reflects data

A substantial portion of the data warehouse effort is spent on reconciling information

Reconciliation Effort

Enables web initiatives to get closer to the source data,both in time and consistency.

BW is closely integrated with R/3, and can deliver data that reflects the source system at short time intervals.

Web delivery requires rapid data delivery of high consistency with the source system.

Web strategy

Substantial cost savings, bynot having to redevelop newextract programs for eachSAP upgrade

BW – R/3 integration points are maintained and tested by SAP

Updating extract programswhen upgrading R/3 is expensive.

Cost Avoidance

SAP is responsible for maintenance of the product.

Maintaining a custom developed BI solution is complex and expensive.

Area Observation SAP BW Benefit

Faster Deployment Need to increase time to deliver new applications and enhancements existing areas

Typical use of 60-80% of pre-delivered content increases development speed

Reduced development time for new decision support areas

Integrated Products SAP continues to offer new products and modules that the organization might wish to leverage in the future

SAP BW is the “cornerstone” of SAP’s New Dimension product offerings

Enables closer integration with other SAP modules

Query speed Business users need fast access to their data

Through use of summaries, TREX, and the new accellerator, SAP BW’s architecture lends itself to faster query performance

Users get the data they need quickly to perform their job functions

Example Business Benefits of SAP BW (cont.)

8

Area Observation SAP BW Benefit

SAP Strategy It is the organization’s SAP strategy to leverage investments in the SAP to the fullest extent, and maximize SAP resource utilization.

SAP BW is a SAP product, and is based on standard SAP NetWeaver technologies (Basis, ABAP, etc.)

Strategic fit and synergy with SAP. SAP Basis, ABAP, etc. resources can be used across SAP projects, including SAP BW.

Tool Standardization

The organization must be able to leverage industry standards to enable business users to access data in a variety of ways

Microsoft’s ODBO application interface and Java (SAP BW 3.5) are supported by a variety of major presentation and web tools.

Simplifies user access to data, expands options for using standard presentation and web tools, or developing your own.

Industry Trend The organization’s competitors and some of the organization’s business areas are installing SAP BW

Increased industry resource pool and knowledge of SAP BW

Enables the organization to leverage industry solutions and know-how.

Identifying Your Business Requirements

• One of the first steps is to gather the right requirements. This is done in a variety of ways, depending on which methodology you employ. It is a complex process involving:

1. Discovery and Education

2. Formal communication

3. Reviews

4. Final approvals

An SAP NetWeaver implementation involves more than just black-and-white technical

decisions; just because something is technically feasible, doesn’t mean it is wise or desirable from a business perspective.

decisions; just because something is technically feasible, doesn’t mean it is wise or desirable from a business perspective.

What user wanted How customer described it How analyst specified it How designer implemented it

11

Defining The Scope Of Your SAP BW Implementation

• First, determine what the business drivers are, and make sure you meet these objectives.

• Define the scope in terms of what is included, as well as what is not included.

• Make sure you obtain approval of the scope before you progress any further. All your work from now on will be driven based on what is agreed to at this stage.

• As part of the written scope agreement, make sure you implement a formal change request process. This typically includes a benefit-cost estimate for each change request and a formal approval process.

Change management is done to manage scope, timelines and competing business requirements.

Note

12

Defining The Scope Of Your SAP BW Implementation (cont.)

• For the first go-live, keep the scope as small as possible e.g., Accounts Payable, Accounts Receivable, G/L, or COPA

• You have only 3 dimensions to work with:

If one of these dimensions changes, you have to adjust at least one of the others

Selecting A Methodology

• Many times, there are several potentially “right” choices i.e., when time-to-delivery is moderate, or when the impact of failure

is moderate

among the appropriateness of each methodology.

The decision is clearer in the extreme. In practice, however, there are “gray zones” where more than one answer may be

correct.

Writing A Milestone Plan

• Use milestone plan to illustrate dependencies and high-level tasks

Developing Your Staffing Plan: Lessons Learned

• Developer training should start early for all project team members

• SAP R/3 skills are not easily transferable to SAP BW Hands-on experience is needed It’s very hard to learn while being productive

• The quality of the team members is much more important than the number of members An experienced SAP BW developer can accomplish in one

day what 3 novice developers can do in a week The tool has a steep learning curve

Note

GOTCHA!

18

Developing Your Staffing Plan: Lessons Learned (cont.)

• Project time and cost estimates should be based on team’s experience level

• Plan on formal knowledge-transfer from external resources from day one Link inexperienced members with experienced ones

• Have identified “go-to” resources available in all areas Make a list!

(we will take a second look at

this when we do the budgeting!)

Budgeting Process Steps

1. Size the SAP BW effort based on the scope

2. Prioritize the effort

3. Map the effort to the delivery schedule

4. Plan for number of resources needed based on the scope, delivery schedule and the effort.

Create the Milestone Plan and Scope Statement first, before attacking the budgeting process!!

Start the budgeting process by estimating the workload in terms of the development effort. Refine based on the team’s skill experience and skill level

We will now lo

the

real world

4. Result: Good Input for the Staffing Costs and Planning

Many companies plan a 60%- 40% mix of internal and external resources for a first go-live. Also, most use $50-$90 per hr for internal budgeting and $90-$170 per hr for external resources.

More Details on workplan writing available here: “Writing Solid and Realistic Work Plans for a SAP BW Implementation Project”, SAP Project Mgmt Conference - Oct. 2005, Las Vegas: http://csc-studentweb.lrc.edu/swp/Berg/articles/PM05_Berg_Writingasolid.ppt

Writing the Workplan

• The Workplan1. Write a detailed workplan that references the methodology.

2. Make sure the workplan is detailed enough to track project progress.

3. Progress can be measured by hours used, vs. % of tasks completed.

32

Monitoring Progress

• Manage the workplan from a percent complete standpoint on a weekly basis

• Create weekly status reports with core progress metrics and send to all team members (keep it high-level and tangible)

• Require monthly status reports from all team members in a fixed format

• Keep a close eye on the deadlines for the deliverables and make to follow-up personally on late tasks

• Track percent complete tasks in the workplan against the number of hours, or days worked, to see if you are on-track.

Note

Warning

SAP BW is a complex environment that has many dependencies. Late tasks can have significant impacts on the overall project.

The User Acceptance Group and Its Role

• Create a user acceptance team consisting of 5-7 members from the various business departments or organizations

• Keep the number odd to assist with votes when decisions need to be made. With fewer than 5 members, it can be hard to get enough members present at each meeting

• Make this team the focus of your requirements gathering in the early phase, then let this team perform user acceptance testing during the Realization phase

• Meet with the team at least once a month during realization to refine requirements as you are building, and have something to show them

Issue

This approach is hard to execute when also managing scope, but is essential to make sure that the system meets users’ requirements

37

7 Key Points to Take Home

• Write the business case around the areas of greatest benefit to your users

Don’t use a “shotgun” approach, keep it focused

• Define your scope in-terms of what is included, and state what is not included

• Establish a formal change control process that is well communicated

• Plan your project based on the hours required for the effort, and the project teams’ experience and skill levels

38

7 Key Points to Take Home (cont.)

• Establish milestone dates, and map the work hours required to these dates

• Establish an “on-boarding” plan for project resources

• Establish a formal process for quality control and approval of deliverables
